SPECIFICATION forming part of Letters Patent No. 651,280, dated June 5, 1900.

Application filed September 8, 1899- Serial No. 729,884. (No model.)

To (all whom it nutty concern:

Be it known that I, JOHN TAYLOR, residing at King I-Ienrys alk, Balls Pond, London, England, have invented certain new and useful Improvements in Bottle-Stopper-lvlolding Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to made and use the same.

This invention relates to improvements in bottle-stopper-molding apparatus, and has for its object to provide means for molding glass stoppers without the side ribs or seams produced upon stoppers molded in the usual manner.

With this object in view the invention resides in the various novel details of construction and in the combination of parts hereinafter fully described, and particularly pointed out in the claims.

In the drawings, in which I have illustrated my invention, and in which like letters of ref-' erence indicate corresponding parts, Figure 1 is a plan view of the complete apparatus with the press-plunger removed therefrom; Fig. 2, a side elevation thereof. Fig. 3 is a plan view of the press-plunger, shown independently; Fig. 4, a similar view of the central plate, the handles being removed therefrom. Fig. 5 is a section on-line x of Fig. 4; Fig. 6, of the base-plate with the upper plates removed and the clips shown open, while Fig. 7 is a section on line Y Y ofFig. 1.

In the drawings the letter a represents a base-plate provided with a plurality of rec-J tangular projections 1), arranged in parallel rows upon its face. These projections b have rectangular openings 0 formed in a transverse manner in same, the said openings ex tending through the projections to a conven ient depth in the plate a. The bottoms of these openings 0 are closed.

cl represents a plurality of flat parallel bars or clips located upon the plate a, such bars or clips,which work in pairs,being recessed upon their opposing sides to form in conjunction with the openings 0 dished or countersunk mouths to such openings. Each pair of bars or clips (1 is carried by transversely-sliding carriers 6, traveling in guide-slots in the face of the base-plate a, the ends of such carriers Lugs a? are provided at one end of the plate a, to which lugs are pivoted at f the ends of two lovers f, such levers also being f ulcru med at f 2 to horizontal projections 6 upon the blocks 6. These levers f have for their function the opening and closing of the pairs of bars or clips (1.

The forward ends of the leversfare supported by wings a upon the forward end of the plate a, such wings being recessed upon their upper surfaces, as at a, to allow the said levers to drop into same when they are pushed toward one another to close the bars or clips (1.

'9 represents a second plate, which is superposed upon the base-plate a, such plate g having end openings g, into which take pins (1 provided upon the ends of the plate a. A plurality of mold-openings g corresponding in number and position with the openings c in the base-plate a, are provided in the said plate g, the lower ends of such openings 9 being enlarged to coincidein size with the mouths of the first-named openings 1). Handles g are provided upon the plate g for the purpose of lifting such plate on and olf the base-plate a.

Hinged between the bifurcated end of a vertical lug 72. upon the rear end of the baseplate a I have a top plate 2', such plate having a rectangular opening 'i' in same to ad- [nit the plunger j of a suitable press. (Not shown.)

Pivotally located in the nose of the top plate 2' is a vertical-spindle 70, whose lower end carries a rectangular'bolt it, formed integral or rigidly fixed to the end of such spindle, the upper sides of such bolt forming shoulders The said bolt takes into a haspZ upon the forward end of the base-plate a, when the top plate't'is lowered upon its hinge, the locking of the said plate to the base-plate through the medium of the bolt is being effected by turning said belt at right angles to the openingin the hasp Z, so as to cause the shoulders it upon such bolt to abut against the under side of the hasp.

m represents a handle fixed to the upper 'end of the spindle for the purpose of lifting and lowering the plate '5 upon its hinge and also for turning the spindle in order to cause the bolt It to assume its locked or unlocked position.

The operation of the apparatus is as follows: The top plate '5 is unlocked from the base-plate and lifted upon its hinge to allow of the removal of the interposed plate g. Each pair of bars or clips at is then brought together by pushing the levers f toward one another. The plate g is then placed in position on the plate a and the top plate 11 lowered upon its hinge and locked to the baseplate in themanner before described. The molten glass is then poured through the opening t" in the top plate 1' onto the surface of the center plate g', which molten glassis then pressed through the mold-openings g by means of the plungerj in the usual manner. \Vhen this operation is complete, the molten glass is allowed to set sufficiently, whereupon the pressure from the press is removed, the top plate unlocked and lifted up upon its hinge, the waste glass sliced off the surface of the plate g in any convenient manner, and the finished stoppers removed from the mold by moving the levers f outward and away from one another, which has the effect of opening the bars or clips d sufficiently to allow of the ready removal of the molded stoppers.

The heads of the stoppers are formed by the openings or sockets in the plate a, the turnouts by the countersunk or dished mouths of such openings, and the turn rece'sses in the pairs of clips or bars, while the shanks of such stoppers are produced by the mold-openings in the center plate g.

VVhat'I claim as my invention, and desire to secure by Letters Patent, is-

1. In bottle-stopper-molding apparatus, the combination of a base-plate havingaplurality of openings in its surface, and a plurality of clips having recesses in their opposing sides and carried by sliding carriers actuated by levers f ulcrumed to one end of said base-plate and to projections on the ends of the carriers; with a central removable plate having openings in same corresponding in number and position with the openings in said base-plate, and a removable top plate having a rectangular opening therein to admit the pressplunger and hinged at one end to the baseplate and locked at the other end to said base-plate, by means of a bolt taking in a hasp on the said base-plate, and operated by a handle, substantially as specified.

2. In bottle-stopper-molding apparatus, the combination of abase-plate havinga plurality of rectangular openings in its surface, arranged in parallel rows, said openings having their mouths countersunk, and a plurality of clips, arranged in pairs upon said base-plate and carried by transversely-sliding carriers working in grooves in the surface of the said base-plate and operated to close and open said pairs of clips, said pairs of clips having their opposing edges recessed to coincide with the countersunk mouths of the openings in said base-plate and forming the sides of said mouths, and levers fulcrnmed to projections on said base-plate and to projections on the end blocks of said carriers, said levers being held near their free ends in recesses in wings upon the corresponding end of the base-plate; with a central plate removably held upon said base-plate and having a plurality of moldopenings corresponding in number and position with the mold-openings in said baseplate and having their under sides enlarged, said central plate having handles for lifting purposes; and a top plate having a central rectangular opening to receive the pressplunger and hinged at one end to a vertical lug upon one end of said base-plate, said central plate having a boltspindle rotatably mounted in its other end to take in a hasp upon the corresponding end of the base-plate and operated to lock said central plate upon the base-plate and to unlock it therefrom by means of a handle fixed to the projecting upper end of said bolt-spindle, substantially as specified.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

J OI-IN TAYLOR.
